Apricot tree PA 7201-1

ABSTRACT

A new variety of apricot tree bearing fruits of very large size, good quality and flavor and exceptional firmness. The fruits of this new variety are characterized by its attractive light orange color overlayed by a reddish purple blush. Its firm, large-sized fruits have long storage and shelf life and are particularly adapted to premium, long-distance fresh markets.

BACKGROUND AND SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of apricottree which bears large to very large, firm, attractive fruits ofexcellent quality and flavor. The fruit is especially well adapted forshipment for fresh markets because of its firmness, long shelf life andexcellent dessert quality.

This new variety of apricot tree was originated at the IrrigatedAgricultural Research and Extension Center at Prosser, Wash. fromcrosses made in 1972. It was selected in 1976 from 92 seedlings of thecross Goldrich X Blenril (both varieties unpatented). Second test treeswere planted on the Roza unit of the Center in 1977 and came intoproduction in 1980.

Flowers of the present variety require cross-pollination. They will setfruits with pollen of one of their parents (the Goldrich variety) andwith Perfection (unpatented). In addition, flowers of the subjectvariety are pollinated by and will pollinate flowers of Apricot Tree PA7221-1 which is the subject of a patent application filed concurrentlyherewith.

In the Yakima valley the fruits of this variety ripen about two weeksbefore that of Wenatchee (unpatented). The round to oval-shaped fruitshave slightly compressed sides and are very large being up to 23/4inches in diameter when adequately thinned. The skin is light orangewith a reddish purple blush covering up to 30% of the surface. It isslightly glossy in appearance. The flesh is very firm and moderatelyjuicy. Some acidity is associated with the skin. Fresh market quality israted as excellent whereas canning quality is poor, becoming mushy whencanned. The fruit most nearly resembles that of variety PA 7221-1. Thesetwo new apricot varieties are meant to be planted together in theorchard as sister varieties since they cross pollinize one another andproduce similar fruits which mature at the same time. Thus, the fruitscan be harvested, packed and shipped together.

Trees of the subject variety are vigorous on the common rootstocks usedfor apricot trees. They bloom heavy but often tend to set relativelylight crops thereby reducing the need for thinning. The extra largeattractive fruits can readiy be tradepacked for premium fresh markets.

Asexual reproduction of this new and distinct variety shows that itsunique characteristics come true to form and are established andtransmitted through succeeding propagations by grafting.

BRIEF DESCRIPTION OF THE DRAWINGS

In the accompanying photographs, vegetative growth and fruit of the newvariety are shown both on and off the tree and are depicted in color asnearly true as is reasonably possible to make in color illustrations ofthis character:

FIG. 1 shows the vegetative growth and fruit of a mature specimen of thesubject variety on the tree.

FIG. 2 shows the stems and leaves along with the whole and half fruitsof the subject variety off of the tree.
